It would be handy in situations like debugging someone else's code and needing to break into the debugger without moving your app into the background.
On Mac OS X it's not quite as straightforward as a hardware NMI. You don't want to interrupt the whole machine, you just want to send a signal to a particular process; how do you tell it which process? (I suppose you could write some global doohickey that sends a SIGINT to the frontmost process. But in general you should just either Command-Option-P (pause) when Xcode is frontmost, or build a "Debug" menu item into your app that calls Debugger() when you want it to.
